Figure 4

Binding of plant-produced RBD to ACE2, the receptor of SARS-CoV-2. Dilutions of plant-produced RBD and commercial CHO-produced RBD (control) were incubated on plates coated with ACE2 and detected with anti-his antibody conjugated with HRP. Non-infiltrated (WT) plant protein was used as a negative control. The data are the mean values of triplicates from each concentration.
